To all whom t may concern.'

Be it known that I, BnNois'r S. REDD, a citizen of the United States, residing at New York city, county of New York, and State of New York, have invented certain new and useful Improvements in Black-V Leading Machines, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to certain improvements in black leading machines.

It is one of the objects of the invention to produce a black leading machine adapted to use a solution of black lead, which will be economical in its construction, certain in its operation, and in which the position of the case may be varied as it travels through the machine, toV insure a thorough application of the solution to the case. Y

A further object of the invention is to produce an improved black leading machine in which the amount and force of the solution delivered to the case may be varied.

A further object of the invention is to produce an improved black leading machine in which the operation of the machine may be interrupted after a case has received a predetermined amount of travel and has thus received a predetermined amount of the solution.

A further object of the invention is to produce an improved black leading machine of such a construction that it may be readily flushed or cleaned by the solution itself.

With these and other objects not specifically referred to in View, the invention consists in certain constructions and certainl parts, improvements and combinations as hereinafter more particularly set forth.

Referring to the draw1ngs- Figure 1 is a side elevation, partly in sec- Y' tion, of a machine embodying the invention;

Fig. 10 is a plan view, partly in section, ofdthe construction illustrated in Fig. 9, an v Fig. 11 is a detail elevation of the constructionillustrated in Figs. 9 and 10.

Machines embodying the invention will include asupply tank for the black lead solution and a delivery boX. While the construction and relative arrangement of these parts may be varied, in the particular construction illustrated the tank is indicated at 1, said tank being supported on a suitable frame indicated at 2. In the best constructions embodying the invention, the bottom of the tank will converge as indicated at 3 toward a central opening indicated at 4.

The delivery boX, in the particular construction illustrated, is located over the tank and is marked 5. This bo-X, for convenience, is provided with a cover 6 held in position by a plurality of C-clamps marked 7. In the best constructions embodying the invention, the delivery boX will have slotted openings so as to deliver the solution in sheetlike form, and means will be provided for controlling the amount of solution delivered through the slotted openings. v While the construction may vary, as illustrated the bottom of the boX is provided with two long slots 8 arranged to overlap at the center of the boX, and bars 9 are provided by which the slots may be either closed altogether, or opened any desired amount.

The means for varying the openings, whatever be their form, and thus varying the delivery of the solution, will be accessible from the exterior of the boX. In the particular construction illustrated, each of the bars 9 is connected by links 10 to the arms 1 1 of bell cranks 11, 12, the arms 12 of this bell crank being connected by bars 13 to handles 14, there being one of these bars 13 and a handle 1lik on each side of the boX. In the construction illustrated, each of the handles 14 cooperates with a toothed segment 15,- by which the handle,and con- 'y This shaft is providedv with an upstanding sequently its corresponding bar, is locked in any position desired, the usual spring pawl (not shown) in such constructions being provided. Y

Machines embodying the invention will include means for passing a case beneath the delivery box. 'Vhile these means may vary, Vin the particular construction illustrated, the sides of the tanks 1 are provided with tracks 16 on which is supported a carriage 17, the carriage being provided with the usual wheels 18 and .with projections 19 which ytake under the track and steady the carriage. The carriage is provided with a downwardly projecting lug 2O which `carries a fork 21, this fork engaging a right and left hand screw 22 supported at one end in a standard 23 rising from the bottom of the box and journaled at the other end in theend of the bo'x.- As shown, this screw is provided with a sprocket wheel`24 over Y which runs a sprocket chain 25, this chain running over another sprocket wheel 26. This wheelv 26 is carried on one end of a shaft, the'other end of this shaft being provided with a miter gear 27 which meshes with a miter 28 on a driving shaft 29. In the best constructions embodying the invention, means will be provided for interrupting the operation of the machine after the carriage which supports the case has been given a predetermined amount of, travel, that is to say,

after the case has received a proper amount of solution. lVhile the means employed for thus interrupting the operation of the machine may be varied, inthe particular construction illustrated (see more particularly Y Figs. 9 and 11) a shaft 30 is provided, this shaft passing through one of the sides of the tank and through one of the tracks 16.

arm 31, and this Yarm carries at its upper end a set screw 32 which is struck Yby one end of the carriage as it completes each reciprocationi The set screw enables the amount of movement of the arm, and consequent throw of the shaft, to be regulated'as desired. The

shaft 30 is provided outside the tank with a pawl carrier 34 in which is mounted a pawl 35. This pawl takes into a ratchet wheel 36,

which is'loosely mounted on the shaft. This ratchet wheel construction illustrated is provided ,with aV plurality of holes 37 in any one of which a pin 38 may be placed. The shaft' 30 also has ,loosely mounted thereon at arm :39, this arm being held up against a stop pin 40'by means of a spring 41. The' arm 39 has connected to its lower end a shippingbar 4:2, this bar being provided with an incline 43 on its outer end, this incline'taking undery a hook 44 which, ywhen thema'-k chine is in operation,` takes over a stud 45 V on the jbelt shipping lever 46. When the pin 38, before referred to, has been brought into'cont'act'with the arm 39, the next reciproc'ation ofthe carriage will rock the arm 39, move the bar 43, and allow the shipping lever, which is urged by a spring (not shown) to move. This movement of the shipping lever rocks a shipper shaft 47, this shaft being provided with a shipper arm 48 which shifts the belt from the fast to the loose pulley of the shaft 29.

In the best constructions embodying the invention, means will be provided for automatically resetting the stopping or interrupting mechanism for the machine. lVliile these means may vary, and will vary according to the character of the interrupting mechanism employed, in the particular construction illustrated there is provided (sec Fig. 9) a two armed lever 49, 50, the arm 50 being connected by a link 51 to the cover 52k of the supply tank. As the cover is raised, therefore, the lever 49, 50, which is pivoted on a stud 53, will be rocked. The arm 49 of this lever is in position so that it will strike the tail of the pawl 35 before referred to, thus disengaging it from the ratchet wheel. In the construction illustrated, a holding bolt 54 is provided, this bolt being impelled against the ratchet wheel by a spring 55. The hub of the two armed lever is provided with a small projection 56 which, when the arm is rocked, comes in contact with a plate 57 secured to the end of this sliding bolt 54. The rocking of the lever, therefore, not only releases the pawl 35, but also the bolt 54. The hub of the ratchet 36 is provided with a spring 58 wliiclnrwhenthe pawls are released, return the ratchet wheel to its normal position.

vIn the best constructions embodying the invention, means will be provided for giving the case a rotary movement so as to insure that the sides of the design on a case shall be so positioned as to insure that all sides of the design, as well as the faces thereof, come in contact with the solution. lVhile the means for effecting this revolution of the case may vary, in the particular construction illustrated the case is carried on a table 60, this table being carried on a depending stud 61 which is swiveled in a hub 62 on the carriage. This stud has secured to its lower end a hub 63 from which extend two pairs of arms 64, 65. The arms 64 are provided with depending studs on which are mounted rolls 66, and the arms 65 are provided with upstanding studs on which are mounted rolls 67. Stops 68, 69 are provided, these stops being located nearv the ends of travel of the carriage, and, as shown, being fast to the bottom of the supply tank. As shown, these stops are located on opposite sides of what may be termed the center line of the tank and the top of stop 68 is in a slightly higher horizontal plane than' the stop 69. As the carriage reciprocates, and as it nears the end of its Amovement to the right, one of the depending rolls 66 will strike the top of the arm 69 and give the table 60 a quarter turn, the arm during this movement swinging over the top of the stop 69. As the carriage is about to complete its movement to the left, roll 67, on one of the arms 65, will strike 4the top of the stop 68 and the table be advanced another quarter turn, one arm 64 during thisv movement swinging under the top of the stop 68. By this construction, therefore, the carriage is given a quarter turn at the end of each half reciprocation of the carriage.

Means will be provided for conducting the solution from the tank toy the delivery box. "Where, as in the construction shown, the delivery box is located-over'the tank, a pump may be employed, such a pump being indicated at 70, this pump being driven by a belt 71 from a pulley 72 on the shaft 29, before referred to. The delivery nozzle of the pump is indicated at 73, and this nozzle has horizontal pipes 74 connected thereto which are in turn connected by upwardly extending pipes 75 with each end of the delivery box 5. The opening 4 in the bottom of the tank has a delivery pipe 76 connected thereto, the intake pipe 77 of the pump connecting with this pipe. This pipe is provided with a valve 79 by which the entire contents of the tank may be drawn ofi' when desired. A strainer, as 80, may be located in the tank over the opening 4.

In the best constructions, means will be provided for iiushing the apparatus. While these means may vary, in the particular construction illustrated the delivery box 5 is provided with an opening, this opening being closed by a plate 81. This plate is mounted on a hinge pin 82, this pin having connected to one of its ends an arm 83. A bar 84 is connected to the arm so that the plate may be opened by pulling on the bar 84. In the construction shown, the intake pipe 75 which is connected to the end of the box nearest the iushing opening is provided with a valve 85 by which this pipe may be closed when it is desired to flush the machine. TWhen this valve is closed, and the plate 8l rocked to open the flushing opening, the solution is caused to circulate in considerable volume through the delivery box and down into the tank, thus clearing the apparatus. rIhe strainer will collect any impurities in the solution, and, as this strainer is removable, it may be taken out and cleaned when the flushing operation is completed.

It may be desired to vary the temperature of the solution, particularly in weather when the solution is apt to become thick or viscous. While this may be eifected in various ways, in the particular construction illustrated a coil pipe 86 is led into and out of the tank, so that either steam, or if it should be desired, a cooling solution, may be conducted through the tank.

As has been indicated, changes and variations may be made in the construction by which the claimed invention is carried into effect. The invention is not, therefore, to be confined to the specific construction hereinbefore described.
